The NFLPA filed a motion Tuesday holding the NFL in contempt of court for what it says is deliberate ignorance of a February court order that overturned former Minnesota Vikings running back Adrian Peterson's suspension.
The NFL failed to comply with an order to reverse its decision in the Peterson case and issue a new ruling consistent with the latest collective bargaining agreement, according to NFLPA president Eric Winston.
"The Union made multiple requests to the League office asking the arbitrator, who serves at the direction of the Commissioner, to comply with the law and avoid further litigation. Despite our attempts, they have done nothing and leave us no choice but to seek this motion," the NFLPA said in a statement.
Peterson was indicted in September in Texas for striking his 4-year-old son with a switch. Peterson was placed on the NFL's exempt list and missed the final 15 games of the 2014 season.
In November, Peterson pled no contest to a count of misdemeanor reckless assault.
While Peterson has three years remaining on his contract with the Vikings, it is unclear which NFL team, if any, he will play for in the 2015 season.
